Description
Technical Field
The utility model relates to an automobile manufacturing field, in particular to automobile suspension spare part.
Background
The plate spring is a common commercial vehicle suspension system component, and when a running road condition is poor or a vehicle turns, the plate spring is easy to twist and move and interferes with a vehicle body bottom beam, a vertical guide plate needs to be installed on one side, close to the plate spring, of the bottom beam, and the plate spring steel plate is prevented from colliding with the bottom beam while the deformation direction of the plate spring is corrected.
The traditional plate spring guide plate is made of steel, and the guide plate is heavy and high in material cost. In order to solve the problems, the existing improvement scheme is to change a guide plate made of nylon, but the strength of the guide plate made of nylon is weaker than that of the traditional guide plate, and the part of the guide plate below a bottom beam is easy to generate permanent deformation under the repeated extrusion of a plate spring; in addition, stress is concentrated at the edge where the guide plate is in contact with the bottom beam, and cracks are easily generated under the continuous impact of the plate spring.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel leaf spring deflector, through the optimization of structure, the problem that the leaf spring deflector of solving the nylon material warp easily and produce the crack.
The utility model discloses a following technical scheme realizes:
the utility model provides a novel leaf spring deflector, includes the rectangular shape platelike nylon plate of installing on the automobile body floorbar through the bolt, and the nylon plate is equipped with the boss of nylon system towards the one side of floorbar, and the boss is located the floorbar below and hugs closely the floorbar lower surface, and the transition face between boss and the nylon plate is the arc surface.
Further: the surface of the nylon plate facing the side of the plate spring is covered with a metal wear plate. The metal wear-resisting plate is more wear-resisting than the nylon board, reduces the deflector and renews the maintenance frequency.
Further: the hardness of the metal wear-resisting plate is lower than that of the plate spring steel plate. The leaf spring steel plate is protected from wear.
And further: the metal wear-resisting plate is fixed on the nylon plate through bolts. The metal wear-resisting plate is convenient to disassemble and assemble and replace.
Further: the radian of the arc surface is the same as that of the folded edge of the bottom beam. The guide plate is more fully contacted with the bottom beam, the pressure is more fully decomposed, and the stress concentration is avoided.
Further: the nylon plate and the boss are provided with a plurality of grooves on the surface of one side facing the bottom beam. The groove can play a role in reducing weight and can increase the heat dissipation of the guide plate.
Further: the nylon plate and the lug boss are integrally cast and molded. Is convenient for manufacturing.
Compared with the prior art, the utility model have following advantage:
1. through increasing the boss, when the leaf spring extrusion deflector made it crooked to floorbar one side, partly on the upper surface decomposes the floorbar through the boss in, avoid stress to concentrate on the nylon board of floorbar dog-ear, reduce the fracture risk.
2. The strength of the lower half part of the guide plate is also increased by increasing the lug bosses, and the deformation risk is reduced.
